A TTORNEY Patented Dec. 17, 1929 Unirse STATES PATENT carica ROBERT G.RED-MANN, F BRISTOL, CONNECTICUT, ASSIGNOB, TO THE SESSIONS FOUNDRYCOMPANY, OF BRISTOL, CONNECTICUT, CORPORATION INGOT 'MOLD Applicationled September i1, 1928. Serial No. 303,592.

My invention relates to improvements in ingot molds, of the form that ismade of cast iron for use in casting ingots of non-ferrous metals, andparticularly of the form that is made-up of a pair of hingedly connectedparts that compose the mold proper and is surmounted by a pouring cupthat is mounted for swinging up and down relatively to the pouringposition and that is particularly adapted l0 for use in producing ingotsin the form of slabs or bars of rectangular or any desired form ofcross-section, and the object of vmy improvement is to incorporate insuch an v ingot mold keeper means for cooperating with the latch membersat the sides of said hingedly connected parts in the form integral lugsthat have relatively elongated contacting holding faces, therebyensuring relatively long life for the parts, and also to provideimproved means 29 for mounting said pouring cup that permits readilyremoving the cup from thje mold structure for the purpose of replacementor the like. y

In the accompanying drawing Figure 1 is a front elevation of an ingotmold that is equipped with latching devices and a pouring cup inaccordance with my invention.

n Figure 2 is a side elevation of the same, an

"o alternative position of the cup being indicated by means of brokenlines.

Figure 3 is a fragmentary front elevation of the upper portion and withpart of the P front mold part broken away.

Figure 4 is a fragmentary side elevation in part broken away to show oneof the cup hinge slots covered by the movable ingot part. p

Figure 5 shows the cup member by itself. 4@ Figure 6 shows the detailsof the keeper lug and the latch arm that engages therewith. My improvedingot mold corresponds in the general features and in the functions ofthe parts under conditions of use to molds that are in common use. Thusthe mold proper is composed of a rear Xed part 10 and a front part 11that cooperate to provide a mold cavity 12 that in the presentinstanceis of rectangular form of crossesection. Said 5a parts 10 and 11 arehingedly connected by means of suitable lugs at their lower ends and apintle-bar 13.

At the upper end .is a pouring cup lllthat is mounted for swinging backand forth and that in the for-ward position is in registration by itsdelivery openings 15 with the mold cavity 12.7'

At the sides of the mold parts 10 and 11 are provided latch means in theform of a latching-bar 16 and a`keeper 17 for cooperating 60 therewith.1

My improvements pertain to the specific form of the keeper 17 that isprovided and to the means for the pivotal mounting ofthe cup 14. i

The latching-bar 16 in each case is pivotally connected toby its rearend 18 to thel rear lixed'part 10 by means of a pintle bar 19 so as toswing downwardly across the side faces of the part-s y10 and 11. At thefront end 70 portion ofthe bar 16 is an engaging lnose 20 thathas acontacting face 21`0f relatively elongated form.

I find it desirable to utilize under holding conditions substantiallythe whole or the l major part of said contacting face 21. I effect thisresulty by providing the keeper lug 17 with a cooperating contactingface 22 that is substantially the counter-part of the face 21. y

Also, as an important detail, the keeper lugs 17 are cast integral withthe front mold art 11.

. Also, the keeper lugs 17 are properly shaped in .the casting, so thatno machining thereof is done in adapting them for they pur- `osedescribed. f

vThe latch bars 16 are drop-forged parts` and the machining thereof is'confined to the rear end 18 for the pivotal connection. 90

\ The steel of the bar and the cast iron of the lug, as diversematerials, cooperate to, assist in providing the holding friction underlocking conditions.

The cast keeper lugs 17 replace a bar of 95 steel, which has been usedheretofore.

A bar has likewise been used for the hinge connection for the pouringcup.`

In lieu thereof I provide integral pivotal lugs 23 at the lower end ofthe cup structure 100 receiving recesses 24 are provided in said up-vper end portion 27 and the pivotal lugs 23 project laterally inwardlytrom the side bars 26 so as to be housed therein.

he recesses 24 are open inwardly towards the mold cavity 12 and underoperating conditions these are closed by the opposed and adjacentportions 28 oit the front moving mold part 11. Thus the cup can befreely removed at any time while the mold is open.

`The advantages of the improved constructions shown and described areemphasized by the fact that ingot molds of the form described arel usedin groups, arranged in a row or vlmounted on a turn-table for ythepouring, and

any weakness that throws a mold out of com mission operates to interruptoperations.

`The latching oit the mold parts must be tight. In the constructiondescribed, the lugs 2f outwear that latch bars.

As to the cups, these burn out. 'Ihe construction described permits oreplacement in situ and without any machining operation ortool-workwhatsoever. f

I claim as my invention l. In an ingot mold having hingedly connectedmold parts that are surmounted by a pouring cup, latch mechanismcomprising a latch bar pivotally connected by one end to one of saidparts andhaving an engaging nose at the other end, a lug on the other ofsaid parts for serving as a keeper in coopera.- tion with said nose, andsaid nose and lug having each a relatively elongated contacting 4facefor cooperating with the face of the other under locking conditions.

2. In an ingot mold comprising a mold proper and a cup surmounting thesame, said mold beingfcomposed of two hingedly connected parts that meetin face-to-face contact, said cup having downwardly projectingsupporting bars, pintle lugs extending inwardly laterally'from saidbars, one of said mold parts having recesses that open from its meetingface and having walls for 1generally enclosing said lugs, and thefaceo'f the other of said mold parts serving as a closure for saidrecesses. Y

3. In latch construction 'for vholdir'ig together the two parts of aningot mold, a

latch bar vpivoted to one'of sai'd parts and having a hook-like engagingnose andl a lug on the other of said parts having ay contact` fact forcooperating with said nose, and said nose and contact face being shapedto provide vthe other, and the structure of at least one of said partsbeing provided with recesses that serve as receiving sockets for saidpintles tor effecting such operative connection. v
